IMPROVEMENT IN CHAIR-SEATS.

Specification forming part of Letters Patent No. 169,944, dated November 16, 1875,' application filed August 7,1875.

ToV all whom it may concern:

Be it known that I, LOEINGr ATwooD, of Rutland, in the county of Rutland and State of Vermont, have invented a new and Improved Wooden Chair-Seat; and I hereby declare that the followin g is a full, clear, and exact description of the same, reference being had to the accompanying drawing, which forms a part of this specification.

Heretofore much difficulty has existed in constructing wooden chairbottoms (when made of more than a single piece of plank) sufficiently strong to withstand the hard usage to which they are continually subjected. This difficulty relates to the methods which have been employed for uniting the strips or pieces ofwood used to construct the chair-bottom.

For instance, heretofore the longitudinal edges have been glued together; but the strips would soon break apart. They have also been united by plain or straight-sided tongues or grooves. but they would pull apart 5 and they have also been united by dowel-pins, but with like result. Of course, they could be fastened stron g enough in many ways; but cheapness in this branch of manufacture is an absolute requisite, and no cheap, and yet strong and durable, way of connecting the strips has, so far as I am aware, been heretofore invented.

My invention consists in the new article of manufacture of a chair-seat composed of two or more strips of' wood united by means of -dovetail tongues and grooves, whereby I produce a simple and inexpensive article, which is extremely strong and durable.

ln the accompanying drawing, Figure l is a plan or top View of a chair-seat made according to my in vention; and Fig. 2 is a transverse section of the same, taken on the plane of the dotted line .r w, Fig. l.

A and B designate the lstrips of wood of which the chair-bottom is composed. In the present instance alternate strips A (three in bottom, may be secured against longitudinal displacement by glue, if desired.

ItA is obvious that by means of my invention I produce a very strong and durable wooden chairbottom-one which is far superior in vthose respects to any others now in the market.

I am aware that wooden strips have heretot'ore been united by means ofdovetailed tongues and grooves for forming barrel-heads; and this I do not claim, my invention consisting essentially in achair-bottom, as an article of manufacture, composed of strips of differently-colored woods, or diiferent varieties of woods, unitedat their edges by means of dovetailed tongues and grooves, which, to my knowledge, has never before been made. Therefore,

What I claim, and desire to secure by Letters Patent, is-

As a new article of manufacture, a chairbottom composed of alternate stripsof differently-colored wood, or different varieties of wood, united at their edges by dovetailed tongues and grooves, substantially as described.

LORING ATWOOD.
